One of the hardest things about being in business for yourself is dealing with the highs and lows of income fluctuation and the resulting cash flow challenges. Not only is this roller coaster mentally and emotionally taxing, but it also makes business decisions—from which bills to pay to growth strategies—incredibly difficult.

When it comes to planning your cash flow, it's all about having an idea of how much money you expect to bring in and how much you expect to send out. The longer you're in business, the more accurate this plan will be because you'll have a steady clientele base and you'll know which expenses are necessary to keep the business running and which expenses are needed to keep it growing.

But how do you budget and create a plan for your cash when you're new to business and have absolutely no idea how much you'll earn from month to month?

Start with your fixed expenses. This is your benchmark or the bare minimum you need to bring in so that your business can keep running. With that total, you can calculate how many services or products you need to sell and at what price. (Learn more about break even analysis.)

Once you've figured out your fixed expenses, take a look at your contracts or invoicing agreements. Specifically, you'll wan to think of your payment terms (i.e., "net 30," "net 15," "due upon receipt," etc.) as they relate to your fixed expenses and their relevant due dates. (Bonus tip: If possible, it is a good practice to establish contract terms that put money in your pocket as early as possible—even up front!)

Next, let's look at three ways to deal with income fluctuation...

Determine how you want to schedule the output. If some of your bills have due dates that you can schedule, take advantage of that. Sure, something like rent isn't going to be that flexible, but your work cell phone bill might be.

Think through your service pricing. Offering your services on a retainer basis can not only help you with immediate cash flow, but also with long-term forecasting.

Make sure the majority of your offerings require at least a percentage payment upfront.
